“He played really well, swung the club well, made the putts when he needed to make the putts, and that’s the way you win,” Horschel said.

The victory was another sign Stallings is moving closer to his 2011 form, when he won nearly $2 million and finished 41st on the PGA Tour money list in his rookie season.

But he’s struggled through much of 2012 because of various injuries – including torn cartilage in his ribs and two herniated disks in his back – making the cut in just five of 18 events before blazing through Annandale. Stallings said the rib injury suffered in January was the most painful, and it took him about five months to fully recover.

He also worked some with a sports psychologist to get back his mental edge.

“I hurt my confidence and hurt everything that came along with it,” Stallings said. “I learned a lot of lessons through that.”

Now he feels fully healthy – physically and mentally.

Annandale was drenched by heavy rain for much of the past week, and the soft, slow fairways and greens led to nearly ideal conditions for low scores.
